UNITED STATES nPATENT OFFICE. 1

AUTOMOBILE SIGNAL.

Application filed February 27, 1922.

' 10 all whom t may concern.'

Be it known that I, VICENTE BoUZA, subject of the King of Spain, residing at I-Iighland Park, in the county of Wayne and 6 State of Michigan, have invented certain new and useful Improvements in Automobile Signals, of which the following is a specification.

This invention relates to a signal device adapted to be mounted upon automobiles, or

vehicles generally, to give notice to following vehicles of an intended turn to the right or left. i

The invention has for an objectto provide a novel |and simple form of signal means for the above purpose, and further to provide a novel control switch for directing the electric current through the signal means.

For further comprehension of the invenf tion, and of the object-s and advantages thereof, reference will 'be had to the following description and Iaccompanying drawings, an'd to the appended claim in which 25 the various novel features of the invention are more particularly set forth.

Fig. 1 is a detail plan view of the control switch.

Fig. 2 is a side view thereof.

Fig. 3 is an end View thereof.

Fig. 4 is a diagram of the wiring circuits.

To control the signal device I provide a switch comprising an insulating base in the centre of vwhich is fixed a post 21 to which is pivoted a pair of oppositely ex tending arms 22. Fixed at one end to the base 10, and extending outwardly under the arms 22 are contact springs 23 provided at points between their ends with contact points 24 adapted to engage the contact heads 25 of binding posts 25 extending through the base 20. The spring contacts 23 are preferably fastened to like bindingl posts 26, the two binding posts 26 being connected together by a flat metal strip Serial No. 539,3 3Q.

27. The outer ends of the arms 22 have insulating blocks 28 on their undersides adapted to engage the ends of the springs 23 to close the contacts 24 and 25.

To enable the arms 22 to be locked in position with the circuits closed I mount on the free ends thereof the bars 30 which are spaced above the arms and are provided with depending legs 31 pivotally connected to the latter 'as at 32. One of the legs of each bar is formed with a downwardly extended hook 33 Which.may be engaged with an eye 34, fixed onthe base 10, by slightly tilting the bars 30 which are normally maintained in horizontal position by the pairs of coiled expansion springs 35 bearing between the ends of the bars and the arms 22. Fixed on top of each of the bars 30 is a push button 36.

In Fig. 4 I have shown the wiring circuits. From a battery 40, or a generator if desired, a wire 41 leads to the central lamp 16, and from the latter a pair of wires 42 lead to the lamps 17 From these lamps 17 wires 43 lead to the fixed contact members 25, while theA spring contacts 23 are connected to the other side of battery 40 by a wire 45.

As will be apparent, a signal indicating a turn to right or left may be given by pushing the proper one of the buttons 36, while if, for any reason such as a block in traffic, it is desired to keep the signal set for any length of time the button is given a lateral movement which causes hook 33 to engage in the eye 34. The control switch may be mounted on the steering wheel, or in any place convenient for the driver.

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows:

A control switch for a vehicle signal comprising a base, a contact arm pivoted at one end to said base and normally eX- tending along the latter in spaced relation thereto, a contact spring iXed at one end to said base and extending alongthe latter under the said arm, a bar spaced above the outer end of said arm and extending, longitudinally of the latter, a rigidly depending leg on said bar midway between the ends thereof pivotally connected to said arm, a pair of coiled expansion springs located between the bar and arm and spaced longitudinally of the bar one on each side of such leeg` to retain it in parallel position with respect to the said arm, a hooked element depending from said leg, and an eye on said base adapted to be engaged by said hook element, by moving` the bar from the said parallel position, and a Contact point carried by said Contact spring at a point between the ends of the latter, the said arm being adapted to engage the said spring Contact adj aoent the free end of the latter to move it to operative position.

In testimony whereof I have affixed my si gnat-ure. Y

VICENTE BOUZA.
